Just saw the video. My favorite part was where they sounded five short twice as to get the island to change course.
Maybe for peeps on board?
It’s the danger signal, it also might be for the passengers.
Either way had the master not sounded it the CG would be up his ass about it.
Curious if there is a mode where losing a generator could cause a loss of continuity (not a short but an open circuit) in the electrical system leading to all the generators going off line?
For many years the US Inland Navigation Rules referred to this signal as the “Danger Signal”. This is problematic. Many mariners were waiting until they were in danger before sounding the signal and thus before taking action for a give-way vessel that was not giving way. The ColRegs are clear that it is a signal to be sounded when in doubt, and not to wait until you are in danger. As of 2014, all reference in the US Inland Rules to a Danger Signal was removed and slowly that information is reaching the mariners. There is no reference to a Danger Signal in the International Rules. Calling it a Doubt Signal sets a better stage for understanding how that signal must be applied.
